Webb28 apr. 2024 · We use atomic shared_ptr operations which are implemented in terms of a spin-lock (most probably that's how it is implemented in the currently available standard libraries). Having a lock-free atomic_shared_ptr would be really benefitial. However, implementing a lock-free atomic_shared_ptr in a portable way can have extreme … WebbThe class template atomic_shared_ptrprovides thread-safe atomic pointer operations over a std::shared_ptr. It provides a better alternative to the non-member shared_ptratomic … WebbIf multiple threads of execution access the same shared_ptr without synchronization and any of those accesses uses a non- const member function of shared_ptr then a data race will occur; the shared_ptr overloads of atomic functions can be used to prevent the data race. template < class _Tp> class _LIBCPP_TEMPLATE_VIS shared_ptr // 3740 { public: green cushions covers
